Ways to Care for Your Back When Sitting

Always avoid slouching.
Use a lumbar backrest for postural support when needed.
Only use a backrest that is comfortable, and / or recommended by your health care provider.
Take periodic breaks from sitting. Stand, and take a short walk whenever possible.
Stretch, and exercise as recommended by your health care provider.
Feet should contact the floor completely when sitting.
Use an adjustable footrest if feet dangle.
You should have 2-3 inches of clearance between the back of your knees, and the front edge of the seat. A chair that is too deep reduces lumbar support, can contribute to slouching, and could lead to pain.
